The Infernal Affairs trilogy (I- III) presents a double infiltration structure between the Hong Kong police force and a triad organization. Its deeper structure is about the psychological destabilization of identity under competing evaluative frameworks not about crime resolution. At its surface level, the narrative follows undercover operations, internal betrayal, and escalating exposure of moles within both systems.

The structural layers of the Infernal Affairs Trilogy

The Layer Architecture

I. Immanent

1. The Hong Kong Crime Story (The Reality):
   The raw, violent, everyday street reality of post-1997 Hong Kong crime and policing. This is the blood, the asphalt, the bodies falling from buildings, and the immediate physical horror of living a double life.
2. The System Theory (The Machine):
   The abstract, institutional structure that drives the reality. It is a compromised system where Valhalla (the Police Hierarchy) and Nibelheim (the Triads) use identical, manipulative tactics. Both systems become structurally compromised and increasingly reproduce similar patterns of manipulation and sacrifice. Gods (Police) and Underworld systems operate to preserve themselves by almost casually destroying and compromising its individual members.
3. The Jungian Layer (The Psychology):
   The internal, clinical collapse. The individual suffer under the weight of internal conflicts and the absence of truth, allowing the “Yan Complex” to become entirely autonomous. This culminates in the psychotic break of Ming, showing all signs possessed by his identification with his hero Yan.
4. The Tragedy Layer (Archetypal images):
   The bridge from the system to the mind, rooted in the traditions of Aeschylean Greek drama and Wagnerian opera. The inevitability of fate where there is no difference between god an underworld, leading to a tragic twilight (Götterdämmerung) where all the good elements—like Siegmund (Yan)—are rejected and the whole Valhalla burns down.
5. The Socio-Linguistic Layer (The Culture):
   The cultural and geopolitical trap of language. This spans from the weaponized Cantonese street intimacy (Ah-Yan / Ah-Ming) used to bind the moles, to the impenetrable Mandarin barrier (Gai tung ngaap gong) spoken by Mainland official Shen Cheng, which isolates Ming and triggers his fatal paranoia.

II. Transcendent

6. The Dantean Framework (The Inferno – Infernal Affair):
   The architecture of structural sin and external psychological hell. In Dante’s symbolic universe, Ming would most naturally belong into the 9th Circle of Treachery, where their specific crimes of betrayal dictate their customized, permanent spiritual punishments (contrapasso). Note the wordplay Infernal.
7. The Buddhist Framework (The Internal Void):
   The cosmic law of Karma: Wu Jian Dao (The Avici Hell). The universe denies Ming the release of his suicide attempt. His punishment is internal, unremitting, and intermissionless—trapping his conscious mind in a permanent, looping fire of his own guilt while his body is paralyzed. We might find Sam there, who is Buddhist. Maybe not.
8. The Confucian Framework (The External Excellence & Morality):
   The destruction of earthly moral harmony. The system forces the characters to systematically mutilate the foundational Chinese pillars of filial piety, mentorship, and brotherhood. By destroying their families and comrades to survive, they fail the ultimate test of external moral excellence, sealing their absolute spiritual damnation.

Dante’s Divine Comedy and Buddhist Avici, “The Hell of No Intermission”

Analyzing the entire Infernal Affairs trilogy reveals a world play connection to Dante Alighieri’s Divine Comedy. The completed trilogy expands into a three-act structure that directly mirrors Dante’s overarching spiritual journey across the Inferno, Purgatorio, and Paradiso.

Inferno — Infernal Affairs (2002): This first film focuses on an inescapable descent. Both the undercover cop Chan Wing Yan—played by Tony Leung Chiu-wai—and the triad mole Lau Kin Ming—played by Andy Lau—enter a deceptive underworld. I will refer them by Ming and others. They lose their true identities and become trapped in a psychological equivalent of Dante’s “9th Circle of Treachery.”

Purgatorio — Infernal Affairs II (2003): This prequel functions exactly like Dante’s Purgatorio by exploring ancestral sins and history. Introducing younger versions of the protagonists—played by Shawn Yue (young Yan) and Edison Chen (young Ming)—the film traces how characters climb a mountain of moral compromise that they can never truly descend. The filmmakers deliberately timed the climax of the prequel to take place on June 30, 1997—the exact night of the China Handover. After 1997, Hong Kong was caught in a geographic and cultural double-bind. The Five Conditions of Avici Hell are quoted. Ming and Yan are the human manifestation of this political schizophrenia. An undercover cop must act like a triad because he sincerely wants to be cop. He has family connection to a high triad boss. A triad mole must act like a pristine superintendent while serving a hidden master.A semi-orphan with no family in Hong Kong anymore.

Paradiso — Infernal Affairs III (2003): This finale acts as an inverted, psychological twist on Heaven. Lau Kin Ming (Andy Lau again) achieves what looks like “Paradise”—he is promoted, decorated, and clear of suspicion. However, because his paradise is built on fraud and the blood of Yan (Tony Leung Chiu-wai), it transforms into his ultimate, customized psychological torture chamber. This essay will focus on the Infernal Affairs III – and only its temporal part. A linguistic shift in Infernal Affairs III (2003) is deeply coded. The first two movies deal with the internal, local culture of Hong Kong (Cantonese) right to the transition. But Part III introduces Shen Cheng (Chen Daoming) speaking Mandarin.

Avici, the “Continuous Hell”

Infernal Affairs III explicitly quotes Avici, the Buddhist “Continuous Hell” or “The Hell of No Intermission” (无间地狱 – Wújiàn Dìyù). What is it? It may hint to ultimate theological destination of the trilogy, binding the Immanent and Transcendent layers together,

The phrase “The Way Without Intermission” (Wu Jian Dao) is the literal translation of the film’s original Chinese title. In Buddhist cosmology, Avici is the lowest, deepest, and most terrifying layer of Hell, reserved for the absolute worst sins—specifically the betrayal of parents, mentors, and brothers.

The ancient Buddhist texts describe Avici with five distinct “continuous” traits that map directly onto Lau Kin-ming’s (Andy Lau) fate at the end of Infernal Affairs III (2003):

• Continuous Time: The suffering has no breaks, no sleep, and no end.
• Continuous Space: The hell is customized perfectly around the sinner; it fills their entire vision so there is no escape.
• Continuous Punishment: The instruments of torture never stop.
• Continuous Rebirth: The sinner dies a thousand times, only to be instantly revived to suffer again.

At the end of the movie physical death would have been a release for Ming. However his His catatonic, paralyzed physical state ensures Continuous Hell. Living hell.

Reading Guardrails

The use of Chinese Names is subtle and the order is Last name, First name. For short reference I prefer the informal Ming (Lau) and Yan. Sometimes you see Lau and Yan, which is mix using his Last name Lau. However, Ming is the street kid becoming a triad mole, while Yan has some influential (though black) family background as we learn in Infernal Affairs II.

I decided to focus on the temporal layer: Hong Kong Crime Story, System Theory Layer and the Tragedy Layer. I keep the Jungian layer and lingo deliberately short. The psychology of the triad leaders would equally interesting.

Anyway, I decided here to change the title of this essay and investigate different angles. Instead of writing patient records of the actors from the Burghölzli (Psychiatric University Hospital Zurich) perspective it seemed to me more appropriate to present two kinships relevant here: system theory (organisational psychology) and tragedy (Wagner’s Opera cycle The Ring and ancient Greek Aeschylus tragedian’s Prometheus). That does not mean I give the other layers less importance. Its more a private interest, since I worked on and off in Hong Kong during 1998-1999 the post-transition years, importantly addressed in the trilogy. This invoked many memories, archetypal images and intercultural connections of this multifaceted fast city and rich culture so aptly presented in this trilogy and also Wong Kar Wei’s movies.

The Movie Plot Infernal Affairs III – a double infiltration

At the narrative level, the police embed officer Yan inside the triad, while the triad embeds Ming and unknown number of other moles inside the police. The movie can also be told as a Tragedy: Ming kills Yan, his Hero; when reference systems converge, truth becomes no meaningful operator anymore. Both agents operate under conditions of sustained secrecy, limited information, and mutual surveillance between systems. Over time, key stabilizing figures are eliminated, and informational channels degrade. This leads to escalating misidentification, compromised operations, and the eventual collapse of both systems’ internal stability. Yan is ultimately exposed and killed, while Ming survives physically but undergoes severe psychological breakdown. After a suicide attempt which he survives, he is irrecoverable injured with a bullet in his brain. Sam and other major figures are eliminated as part of the broader systemic collapse

Infernal Affairs Trilogy DVD cover: Ming (left) and Yan (right)

Infernal Affairs has two parallel timelines:•

• Post-Yan timeline (after Infernal Affairs I)
  • Lau Kin-ming (Ming) is now living with the consequences of Yan’s death.
  • He is separated from Dr. Lee.
  • He becomes obsessed with proving to himself that he is a legitimate police officer rather than a triad mole.
  • He starts investigating another senior officer, Yeung, because he suspects Yeung may also have had connections to Sam’s criminal network. In part, Ming is genuinely investigating corruption, but he is also projecting his own guilt and paranoia onto others.
• Earlier timeline (before and during the events of Infernal Affairs I)
  • The film frequently cuts back to events that occurred before Yan died.
  • These scenes show interactions among Yan, Ming, Sam, and Shen Cheng (the mainland officer).
  • Many of these flashbacks reveal information that was hidden from the audience in the first film and provides new context for characters’ motivations.
• The flashbacks in Infernal Affairs III are usually fairly easy to identify because:
  • Yan (Tony Leung) is alive in them.
  • Ming’s appearance is slightly different.
  • The police hierarchy and ongoing investigations correspond to events before the climax of the first film.
  • Shen Cheng (the mainland undercover officer) is still active
  • The police hierarchy and ongoing investigations correspond to events before the climax of the first film.
  • Shen Cheng (the mainland undercover officer) is still active.

The obvious question: Why does the triad mole Ming suspect and investigate Superintendent Yeung

Ming investigates Superintendent Yeung (Leon Lai) out of a desperate survival instinct that morphs into a profound psychological delusion.

Yeung is the rising star of the Security Bureau. He is cold, brilliant, and ruthlessly efficient. Ming notices that Yeung is acting suspiciously, secretly meeting with a mysterious Mainland businessman (Shen Cheng). Because Ming is terrified of being exposed as the final mole, he begins investigating Yeung to find blackmail material or frame or unmask Yeung before Yeung can catch him. He has becomes suspicious of his connection to Shen Cheng (Chen Daoming), However the linguistic and cultural border makes it absolutely impossible for someone from the Mainland, like Shen Cheng, to ever be a mole for a local Hong Kong triad boss like Hon Sam. Same is true for the pay grade of Yeung.

Psychologically, Ming is desperate to erase his criminal past and truly “become a good guy.” In his broken mind, the only way to prove he is a good cop is to catch a traitor. He projects his own dark secret onto Yeung. Ming convinces himself that if he can expose Yeung as a triad mole, he will finally earn his salvation and cleanse his own soul

• On the surface, because he suspects corruption.
• Psychologically, because he is trying to distance himself from his own past as a mole and convince himself he can be a “clean” cop.
• As the film progresses, it becomes clear that his guilt and deteriorating mental state are driving much of his behavior and lead to his complete break down.

This realization completely unravels Lau Kin-ming (Ming) and seals his tragic fate. Here is how the trilogy structurally and culturally proves why a Mainland mole for Sam could never exist:

The Cultural Glass Ceiling on which Sam and Ming fail

In Infernal Affairs I and II, we see how Hon Sam builds his empire. His recruitment of moles is deeply personal, local, and rooted in the Hong Kong streets. He took young, vulnerable Cantonese street kids—like a young Lau Kin-ming (Edison Chen)—and raised them.

Sam could never replicate this with a Mainland operative. The cultural divide, the intense scrutiny on Mainland-Hong Kong border crossings, and the starkly different law enforcement systems meant Sam could never infiltrate or manipulate a Mainland figure like Shen Cheng. To Sam, Mainlanders were purely a business transaction to get guns or drugs—never people he could truly trust or control.

Ming’s Paranoia and his Tragic Miscalculation

Because Lau Kin-ming is losing his mind in Infernal Affairs III (2003), he projects his own reality onto everyone else.

• Ming knows he is a mole.
• He knows Yan was a cop masquerading as a triad.
• Therefore, in his broken, paranoid mind, he assumes everyone could be a double agent.

Ming suspects that Superintendent Yeung (Leon Lai) and Shen Cheng are secretly working together as a new network of moles for the deceased Hon Sam. Ming completely ignores the language and political border because his guilt has blinded him. He fails to see that a high-level Mainland security official would never take orders from a local Hong Kong street thug.

The Mandarin Connection – Ming‘ unsubstantiated proof that Yeung and Shen Cheng are trad moles.

Ming falls into a tragic trap because he completely misreads the political and linguistic reality of post-1997 Hong Kong.

• The Tapes of the Past: Ming steals secret audio recordings of meetings between Yeung, Shen Cheng (Chen Daoming), and the late Hon Sam. In these tapes, they sound like they are plotting criminal activities. Because Ming is looking for a conspiracy, he takes these recordings at face value.
• The Real Truth (The Counter-Operation): What Ming fails to understand—due to his lack of knowledge about Mainland networks—is that Shen Cheng was a undercover Mainland Public Security official all along. Shen Cheng had infiltrated Hon Sam’s triad network from the Mainland side. Superintendent Yeung was not a triad; he was simply working a highly classified, cross-border counter-espionage operation with Shen Cheng to bring Sam down from the inside.
• The Psychological Break: By the climax of the film, Ming’s mind fractures completely. He hallucinates that he is Chan Wing-yan. When he marches into the police headquarters to arrest Yeung, he thinks he is the heroic undercover cop finally exposing the villains. He plays the tape out loud, expecting the entire police force to arrest Yeung and Shen Cheng. [1]

Instead, the tape only proves that Ming was the one obsessively stalking his colleagues. He completely miscalculated the language of state authority for the language of the underworld. When the illusion shatters, Ming realizes he hasn’t caught any moles—he has only trapped himself.

The climax – office shootout

This misunderstanding leads directly to Ming’s ultimate downfall in the police headquarters:

• Ming believes he is exposing Yeung and Shen Cheng as triads.
• In reality, because Shen Cheng is a legitimate Mainland Public Security official, he was working with Hong Kong Internal Affairs to clean out the police force.

When Shen Cheng and Yeung speak to each other in their precise, official Mandarin, they aren’t speaking the language of a criminal underground. They are speaking the language of state authority. By the time Ming realizes that Shen Cheng could never be Sam’s mole, he has already exposed himself as the real traitor. He is left trapped in his wheelchair, paralyzed and isolated in his own mind—the ultimate “Living Damned” in his self-made Inferno.

A triade mole kills Yan and Ming kills his fellow mole (flash back)

Officially, they were peer law enforcement officers. Lau Kin-ming was a Senior Inspector in the Criminal Intelligence Bureau (CIB). Inspector B was a fellow inspector within the same police unit. On paper, they were simply colleagues working cases side-by-side.

Unofficially, they shared a dark, deeply hidden mirror relationship. Both men were moles planted inside the police force by triad boss Hon Sam (Eric Tsang). Crucially, they didn’t even know about each other’s secret identities until the very end of the first film. Hon Sam kept his moles entirely separated so they could never compromise one another.

When Inspector B ambushes and kills Chan Wing-yan (Tony Leung) on the elevator roof, he thinks he is saving a fellow triad brother. He proudly reveals himself to Ming, expecting solidarity. Instead, because Ming is desperate to erase his criminal past and “become a good guy,” he immediately shoots B to silence the final link connecting himself to Hon Sam.

Ming investigated for Inspector B’s Death (his cover story cleared)

The investigation into Ming at the beginning of Infernal Affairs III (2003) is a standard, highly sensitive internal review following a multiple-fatality shooting involving police officers.

• The Cover Story: After killing B, Ming constructs a carefully calculated lie for Internal Affairs. He claims that Inspector B was the true triad mole. He tells the investigators that B held Yan hostage and shot him in the head, forcing Ming to return fire and execute B in a desperate act of retaliation and defense.
• The Suspicion: While the police force initially accepts B as the scapegoat to close Yan’s murder case, the internal hierarchy doesn’t completely buy Ming’s clean exit. The sequence of events on that rooftop and in the elevator was too messy, and both dead men (Yan and B) were intricately connected to Hon Sam’s syndicate.
• The Demotion: Because of the immense gravity of having two inspectors and a deep-cover officer dead or compromised in a single afternoon, Ming is stripped of his active authority. He is demoted to a tedious, low-clearance administrative duty desk while Internal Affairs thoroughly scrutinizes the forensic evidence and his psychological profile.

This exact investigation is what triggers Ming’s downward spiral into absolute madness in the third film. He is trapped doing paperwork, knowing that if the police dig just an inch deeper into Inspector B’s past, they will find the breadcrumbs that lead straight back to him.

The role of Dr.Lee

Then there is Dr. Lee, a police psychology counsel which is a strong clue there is a depth psychology layer as well. There are quite a few other hints. I will touch two examples in a chapter further on.

Dr. Lee is not just Ming’s wife/ex-wife; she represents the life Ming wanted to have as a genuinely good man with a strong Ego. In Infernal Affairs I the couple is presented as a bright and professional Hong Kong upper middle class couple starting a life together, Throughout the trilogy, she is one of the few people who sees the possibility of a decent person beneath Ming’s deception. When she learns the truth, that relationship becomes another casualty of the lies he built his life on and cost Van’s life, who she treated on behalf of the police and learned to like.

So after Yan’s death, Ming has several overlapping motives:

• Guilt — He knows Yan was the real hero.
• Self-preservation — He wants to erase evidence of his own criminal past.
• Identity crisis — He no longer knows whether he is a gangster pretending to be a cop or a cop who once worked for gangsters.
• Dr. Lee — She loved the version of Ming she thought existed. In a sense, that version was closer to the moral integrity that Yan actually possessed.

There’s a tragic irony here: Ming spent years stealing Yan’s position in the police hierarchy, but after Yan dies, he begins trying to steal something even more impossible—Yan’s moral identity and authenticity.

The film suggests that Ming envies Yan not only because Yan was admired or because Dr. Lee respected him, but because Yan had something Ming never had: a coherent sense of self. Yan suffered terribly, but he knew who he was. Ming achieved status, success, and relationships through deception, so when the deception collapses, he is left wondering who he really is.

That’s why the ending of Infernal Affairs III is so bleak. Ming doesn’t merely miss Yan; he becomes obsessed with him. Yan turns into a kind of moral benchmark, almost a ghostly presence in Ming’s mind. Ming wants redemption, but he also wants something impossible: to rewrite the past so that he could have been the man Yan was.

Whether Dr. Lee specifically loved Yan is left somewhat ambiguous, but it is clear that she comes to respect Yan’s authenticity and sacrifice. As analysis session she let him sleep one hour on her psychoanalytic couch; Alone. One hour safety. Maybe she is impressed how he holds together under pressure and by his boyish charm he till keeps).

Ming understands that. Part of his pain is realizing that the qualities Dr. Lee valued most were precisely the qualities he lacked when he chose to become Sam’s mole. In that sense, certainly: losing Dr. Lee reinforces Ming’s desire to become “another Yan.” The tragedy is that wanting to be Yan and actually having lived Yan’s life are two very different things. Yan earned his integrity through years of sacrifice; Ming tries to acquire it after the fact. That’s the gap he can never fully close and one of the trilogy’s central paradoxes:

• Yan is living a lie, but he remains authentic.
• Ming is living a lie, and gradually becomes the lie.

Yan’s undercover identity is a professional disguise. Internally, he never stops identifying as a police officer. In fact, much of his suffering comes from holding onto that identity despite years in the triads.

Ming is the mirror image. He starts as a triad mole inside the police, but over time he genuinely wants the status and respect of being a cop. The problem is that instead of reconciling the contradiction, he keeps covering it up. By the third film, he barely knows who he is anymore.

Then there is Yeung not another undercover mole in the same sense as Yan or Ming. The film deliberately encourages Ming to suspect that Yeung was secretly connected to Sam and may have protected or benefited from Sam’s network. Ming becomes convinced that Yeung is another hidden traitor. However, much of this investigation is driven by Ming’s paranoia. He starts seeing corruption everywhere because he knows corruption existed in himself.

Who knows Yan’s true identity?

The crucial point from the first film is that very few people knew Yan was an undercover police officer. After Superintendent Wong’s death, the number of people with definitive knowledge became extremely small.

In Infernal Affairs III, Yeung possesses information and files relating to Yan and the undercover operations. This is one reason Ming becomes suspicious of him. Ming starts connecting dots and wondering how Yeung knows what he knows.

Without spoiling every detail of the ending, the film ultimately reveals that Ming’s theory about Yeung is not as solid as he believes. Ming is partly investigating a real mystery, but he is also constructing a narrative that allows him to externalize his own guilt. If there is another traitor, another corrupt insider, then Ming is no longer uniquely guilty.

How many moles were actually in the organisation?

In the reality of the Infernal Affairs III movie, there is only one remaining major triad mole inside the police force during the events of 2003: Lau Kin-ming himself.

By the time the third movie takes place, the other triad moles that Hon Sam (Eric Tsang) planted in the police force have already been dealt with. Inspector B (Lam Ka-tung): The mole who shot Yan on the elevator roof in the first film. Ming shot and killed him immediately after to erase any link to himself. The 5 Moles Exposed by Yeung: Early in Part III, Superintendent Yeung Kam-wing cleanly exposes and arrests a handful of low-level police officers who were secretly on Sam’s payroll.

Once those low-level moles are wiped out, Ming is entirely alone. He is the last ghost standing, which is exactly why his paranoia reaches a fever pitch. He has no allies left, and the walls are closing in.

3.

Ming’s Failed Suicide as Permanent Dissociation

Your observation that he is on the way to a “falling apart suicide” highlights the ultimate, devastating conclusion of the trilogy.

When the illusion inevitably shatters inside the police headquarters—when he realizes he cannot rewrite history and that he has just murdered Superintendent Yeung (Leon Lai)—the autonomous complex collapses under the weight of reality.

• The Attempt: Ming turns his actual service weapon on himself and shoots himself through the chin. This is a desperate, physical attempt by the remnants of his shattered Ego to escape the unbearable horror of his existence.
• The Continuous Hell: The final scene of him paralyzed in the wheelchair signifies a state of permanent, irreversible dissociation. His Ego did not get the mercy of death. Instead, his conscious mind has completely shattered and drowned. He is left trapped in a vegetative state, where his finger eternally taps out Morse code—symbol of the “Yan” complex ruling over a dead mind?

The psychology layer – Ming’s obsession

By the time of Part III, Yan is dead. But Ming is obsessed with him.

When the film cuts to replay Infernal Affairs I from Yan pointing the gun at Ming to the present-day scene ( in the hospital Infernal Affairs III) Ming pointing a finger into the air, we’re no longer watching a simple flashback. The movie is entering Ming’s subjective experience. The physical reality has completely vanished, but the psychological obsession has taken over. The Tragic Meaning: There is no one there. There is no real gun. He is pointing an invisible weapon at his own ghost. He is trying to perform a ritualistic exorcism of his own past, attempting to rewrite history by forcing himself into Yan’s heroic shoes.

The Hallucination: Ming’s mind has fractured so deeply that he believes he is Yan standing on that rooftop.

The Empty Gesture: He raises his hand, shapes his finger into the form of a gun, and points it into the empty air. He speaks Yan’s exact words: “Sorry, I am a cop.”

The “finger pointing” Yan is often interpreted as:

• Ming’s memory of Yan,
• Mings guilty conscience,
• a psychological projection,
• his I/Ego is temporarily taken over
• almost a ghost-like figure judging him.

Not a literal ghost—the film isn’t supernatural—but the simplest interpretation is that Yan has become a presence as a complex in a Jungian definition in Ming’s mind.

The original gun scene

In the first film, Infernal Affairs (2002), Yan holds a real gun to Ming’s head on the sunlit rooftop. When Ming begs for a chance, saying, “I want to be a good guy,” Yan delivers the devastating moral judgment: “Sorry, I am a cop.” In that moment, Yan holds all the moral power. He is the true hero, and Ming is exposed as the fraud. After Yan has exposed Ming, Yan points a gun at him. Ming says something like:

“Give me a chance.”

Yan replies:

“How do I give you a chance?”

Then comes the famous line:

“Sorry. I’m a cop.”

The point is not literally “you’re not a cop.” Ming is a police officer by employment. Yan means to say:

“I am a real cop. My loyalty is clear. You are a mole. I can’t just let this go.”

It’s a statement of identity. After years undercover, Yan is finally reclaiming who he is.

The psychoanalysis couch scene

The scenes where Ming and Yan appear to occupy parallel spaces—sometimes sitting, facing each other, or sharing visual compositions—are generally not time shifts.

They are cinematic representations of Ming’s mental state.

Think of them as:

Ming imagining a dialogue with Yan.

Or:

Ming measuring himself against the dead man he can never become.

The film frequently blends:

• actual flashbacks,
• memories,
• fantasies,
• hallucinations,
• symbolic imagery.

Sometimes it doesn’t clearly signal which one you’re seeing because the audience is meant to experience Ming’s confusion or destruction.

The System Layer – The Machine

Competing Reference Systems

At the structural system level, the trilogy can be understood in terms of competing reference systems—internal frameworks through which individuals interpret reality and evaluate their own actions. Two dominant systems are present: an institutional system grounded in law, hierarchy, and procedural legitimacy, and a criminal system grounded in loyalty, survival, and internal group coherence. Each agent operates not only within a role, but within an inherited evaluative logic that determines what counts as acceptable behavior.

Two cross compromised Systems

The central mechanism of the trilogy is the forced migration of individuals across these reference systems. Yan, originating from the institutional system, maintains a stable police internal reference structure even while embedded in the criminal environment. This produces high psychological coherence but increases external vulnerability. As his police institution is compromised by Sams moles, only his (integer) handler shield him from this danger. After his got killed he is basically without exposed to the degraded compromised police system. Ming, by contrast, originates from a criminal logic and becomes embedded within the institutional system. His adaptability allows survival and advancement, but at the cost of increasing internal inconsistency as conflicting evaluative standards accumulate.

AI generated to the text of this chapter plus a few aesthetic hints . The background is an archetypal snapshot of the city’s visual identity and silently reminds that many competing reference systems are embedded within.

Hong Kong, 1998–1999

The accompanying above image was generated from this chapter together with a few aesthetic cues. Unexpectedly, it captured almost exactly the Hong Kong I remember from working there during 1998–1999: the Kowloon waterfront looking across Victoria Harbour toward Central. Whether geographically exact is beside the point. What struck me was not its documentary accuracy but its atmosphere.

For me, the city view is more than a backdrop. It is the silent protagonist of Infernal Affairs. Beneath its spectacular skyline operated an extraordinarily dense network of information, finance, policing, organized crime, languages, and political transition. It felt less like a conventional static city than a fast living continuously adapting system. That intuition became one of the starting points for the systems-theoretical reading developed in this essay.

It is therefore fitting that the visual language of Infernal Affairs carries echoes of Wong Kar-wai’s Hong Kong. Christopher Doyle, Wong’s longtime cinematographer, served as visual consultant on the film and helped shape its distinctive urban aesthetic together with Andrew Lau and Alan Mak. The city becomes more than scenery; it silently reminds us that every personal tragedy unfolds within a larger adaptive environment whose structures shape, constrain, and sometimes overwhelm individual lives.

Individual degradation

When individuals are required to operate under incompatible reference systems without stable integration, identity coherence degrades. Decision-making becomes unstable, evaluative criteria shift over time, and self-reference loses consistency. At the institutional level, this produces organizations in which trust is replaced by inference, and procedural legitimacy is undermined by informational fragmentation. The system no longer functions as a coherent structure but as a network of competing internal logics.

Institutional System Break down

The Infernal Affairs trilogy (Infernal Affairs, Infernal Affairs II, Infernal Affairs III) can be understood as a structural model of institutional breakdown under conditions of reciprocal infiltration, where multiple incompatible “reference systems” begin to coexist within the same organizational space. A reference system here means the internal evaluative framework through which agents interpret events, assign meaning, and decide action—such as legality and duty in the police system, or loyalty and survival logic in the triad system. Under normal conditions, such systems remain separated: each organization maintains its own internal logic, even when they oppose one another externally.

The central destabilizing mechanism in the trilogy is the sustained insertion of agents carrying foreign reference systems into opposing systems. Yan operates inside the triad while retaining an institutional-police reference structure; Ming operates inside the police while carrying a criminal-adaptive reference structure. In isolation, such infiltration can be contained: the individual maintains internal compartmentalization, and the host system continues to function according to its dominant logic. However, the trilogy escalates this condition beyond containment through long-term reciprocal infiltration, repeated exposure between systems, and the removal of stabilizing intermediaries (handlers, supervisors, and trusted nodes of verification).

Boundary eroding

As a result, the boundary between reference systems begins to erode. The police system no longer operates purely according to legal-procedural logic, but increasingly incorporates inference-based, survival-oriented reasoning characteristic of the triad environment. Conversely, criminal operations become partially structured by surveillance logic, procedural anticipation, and counter-inference. This produces a hybrid system in which neither reference framework remains fully dominant. Decision-making becomes increasingly dependent on partial information, inferred intent, and positional advantage rather than stable rules or shared verification.

Within this degraded structure, truth does not disappear, but loses its operational function. It continues to exist as informational content distributed across different actors, but it no longer functions as a stable coordinating operator that aligns perception, decision, and institutional response. This occurs because verification pathways are fragmented, trust between nodes is compromised, and the act of revealing truth often carries direct strategic cost. Consequently, truth becomes epistemically present but politically inert: it may be known in fragments, but it cannot reliably reorganize the system or restore coherence once disclosed.

Psychological Dimension

The psychological dimension mirrors this system degradation. Agents are forced to operate under incompatible reference systems without stable reconciliation. Yan maintains coherence by anchoring identity to an external institutional standard, which increases his exposure within the hostile environment. Ming, by contrast, adapts fluidly across systems, but this adaptability gradually erodes internal consistency, producing oscillation between evaluative frameworks and eventual identity destabilization. The institutional system thus produces divergent failure modes depending on whether coherence or adaptability is prioritized under conditions of systemic ambiguity.

System Fragmentaton

Ultimately, the trilogy suggests that institutional system collapse does not require the absence of structure, but can emerge precisely from excessive structural overlap without stable integration mechanisms. When reference systems contaminate one another and truth loses its coordinating function, the organization no longer behaves as a unified decision system. Instead, it becomes a fragmented network of competing logics in which actions remain possible, but coherent system-wide orientation is no longer recoverable. in short, he fights on his own.

The tragedy – The slaying of Siegfried, the Hero.

Heros’ suffering

This brings the Wagnerian layer to its ultimate, tragic conclusion. In Götterdämmerung, Hagen stabs Siegfried in the back to steal his power. But in Infernal Affairs, Ming’s punishment is far more terrifying: Mings causes the killing of his hero (by Inspector B), only to realize that the hero’s purity was the only thing he actually wanted.

Mingi s trapped in a perpetuous cycle. He cannot be Lau Kin-ming anymore because his guilt is too heavy, and he cannot be Chan Wing-yan because his hands are covered in blood. He is left standing in the wreckage of his own mind, wielding an invisible identity, completely lost in the “Way Without Intermission.”The trilogy demonstrates how structural conditions determine psychological outcomes: coherence becomes a liability under hostile environments, while adaptability becomes a source of internal fragmentation. The result is a tragedy in which neither survival nor integrity is fully sustainable under conditions of sustained institutional and informational contradiction. For Yan its worse, he finds himself as undercover agent working for a low/zero trust institution which involves him in reckless planned operations let alone being undercover within the triads a second low/zero trust environment. Like Wagner’s Ring cycle does the trilogy not openly distinguish between good and bad. Only a few can assumed being as good: Yan, Dr. Lee, Siegfried, Brünnhilde.

Ultimately, the Infernal Affairs trilogy suggests that when agents are forced to operate across incompatible reference systems without mechanisms for integration, both individual identity and institutional stability degrade in parallel. The tragedy is not moral failure, but the structural impossibility of maintaining coherent self-reference within a fragmented and contaminated system.

Vahlhalla burning down

Both Wagner’s Ring cycle and Infernal Affairs depict systems that collapse under internally generated contradictions, but while Infernal Affairs collapses through informational and identity contamination, Wagner’s world collapses through a foundational corruption embedded in the very logic of power itself shared by Gods an Underworld.Like Wagner’s Ring cycle, Infernal Affairs depict a system that collapse under internally generated contradictions, but while Infernal Affairs collapses through informational and identity contamination, Wagner’s world collapses through a foundational corruption embedded in the very logic of power itself. It needs to be noted however, that it least it seems to me that Ming has reason to believe that the foundational corruption embedded in the police itself. After becoming psychological destroyed by living two reference systems he sees only one logical resolve for himself as both reference systems turned out questionable, to run amok and kills himself.

The Infernal Affairs trilogy can be read as a study of how institutions destabilize when multiple, competing reference systems are introduced and gradually contaminate one another through prolonged infiltration. Within the police–triad structure, each actor operates according to an internal evaluative framework—law, loyalty, survival, legitimacy—that serves as a reference system for interpreting reality and guiding action. Through reciprocal infiltration, these frameworks cease to remain compartmentalized and instead begin to influence institutional decision-making itself, producing a hybrid and increasingly unstable organizational logic.

Truth does not disappear, but it loses its operational function.

In this condition, truth does not disappear, but it loses its operational function. It continues to exist as information, dispersed among different actors, yet it no longer coordinates belief, action, or institutional correction in a consistent way. Fragmented information pathways, degraded trust, and incentives that discourage disclosure transform truth from an effective organizing principle into politically and institutionally inert knowledge. The institution becomes “polluted” in the sense that its original reference structures no longer dominate. Its capacity to stabilize identity, assign meaning, and resolve uncertainty gradually collapses under internally generated contradictions.

Self Destruction

In this respect, again the trilogy invites comparison with Richard Wagner’s Ring cycle. Both works depict systems that ultimately destroy themselves through contradictions generated from within rather than by external enemies. The mechanism, however, differs fundamentally. Infernal Affairs portrays collapse through informational fragmentation, reciprocal infiltration, and the erosion of institutional identity. Wagner’s Ring presents a world whose destruction follows from a corruption already embedded in the logic of power itself.

The tragedy of Ming provides the trilogy with its deepest psychological dimension. Unlike Yan, who preserves his identity at the cost of his life, Ming survives physically while progressively losing the coherent self that once enabled him to navigate between worlds. Having lived for years within two competing reference systems, he reaches a point where neither offers a stable foundation for identity or action. His psychological disintegration is not merely personal but reflects the collapse of the institution that shaped him. The police organization no longer represents an uncontaminated moral order, while the criminal world offers only a return to the logic that originally corrupted him. The result is a state in which no internally consistent reference system remains.

Gods and Underworld fall – Human Cost

Whether one interprets Ming’s final violence and suicide attempt clinically, psychologically, or symbolically, they represent the collapse of a personality that can no longer reconcile incompatible identities. In this sense, Ming recalls Wagner’s tragic figures, although with an important inversion. He destroys the man who embodied the integrity he could never achieve—Yan, his moral counterpart and hero—and ultimately turns his violence upon himself. If Brünnhilde’s self-sacrifice purifies a world whose foundations have become irredeemably corrupted, Ming’s self-destruction offers no comparable redemption. It reveals only the human cost of a world that has lost the capacity to distinguish appearance from identity, loyalty from betrayal, and ultimately truth from the mechanisms by which power sustains itself.

You may say, what about Wotan and Zeus? True, there were god’s, philandering though with humans, creating all sorts of tragedies and not much better if at all than the underworld. Easy to find synonym for gods. Immortality was sometimes a burden even to Wotan. Wotan’s favorite daughter Brünnhilde gave immortality away easily when she saw even the problematic love between Sigmund and Sieglinde, the incestuous parents of Siegfried. Brünnhilde followed her love Siegfried emasculating herself by jumping with her beloved horse into the burning, crashing Valhalla. Ming#s suicide attempt was not so lucky. We do not know where he ends up, but one can assume it might not be the same place as Brünnhilde, Siegfried, Yan.

Identities are formed by the Worlds they inhabit

Institutions shape the reference systems through which individuals construct meaning. When those system reference systems become contaminated, they no longer merely fail to protect integrity—they actively undermine it. The tragedy of Infernal Affairs is therefore not simply the corruption of individuals, but the corrosion of the very frameworks that make integrity possible.
Perhaps the enduring power of Infernal Affairs lies in the fact that it never asks whether good people can survive in a corrupt institution. It asks a more disturbing question: What happens when the institution itself can no longer provide a coherent reference system for distinguishing truth from appearance, loyalty from opportunism, or integrity from successful performance?

If that question is taken seriously, the trilogy ceases to be merely a crime drama. It becomes a tragedy—and of the people whose identities are formed by the worlds they inhabit.

Conclusion

In that sense, Infernal Affairs belongs to a much older dramatic tradition. Like Wagner’s Ring, it portrays not the triumph of good over evil, but the collapse of an ambiguous world whose internal contradictions have become irreconcilable. Its protagonists are neither heroes nor villains in any simple sense; they are individuals caught within systems that no longer provide a coherent framework for identity, loyalty, or truth. The tragedy lies not only in their deaths, but in the destruction of the very structures that once gave their lives meaning.

Aeschylus’s Prometheus Bound and Wagner’s Ring are widely studied together, not as opposites, but as direct spiritual and structural kin. Readers may find different symbolic resonances—in Wagner, in Greek tragedy, or even in contemporary political conflicts. Such parallels should not replace the films themselves, but testify to their remarkable capacity to illuminate the recurring relationship between identity, power, and the fragile operational role of truth. We started with what looked like a straightforward crime trilogy. The depth psychology perspective hinted in the film cannot be ignored, but the needed underlying analysis is more structural and, in my view, has explanatory power beyond these trilogy. By the end, we had arrived at a coherent interpretive framework built around a tragedy with value reference systems, system contamination, identity coherence, and the fragile operational role of truth.
